Cathodic Protection for Reinforced Concrete Bridge Decks
The first three cathodic protection systems installed on PennDOT decks are the focus of the report. PennDOT's first cathodic protection system was constructed in 1977 on U.S. Traffic Route 15 near Allenwood. It used high silicon-chromium iron anodes and a conductive bituminous interlayer. In 1982, PennDOT constructed a non-overlay cathodic protection system on U.S. Traffic Route 15 at the New Columbia interchange with anodes placed in slots backfilled with a conductive polymer. The system was potential controlled with secondary anodes spaced two feet apart. The report describes the construction of PennDOT's second and third cathodic protection systems. It also includes costs, performance, and rehabilitation information. Bituminous mix stability problems were encountered on the Allenwood deck. Problems associated with the conductive polymer slot backfill material such as cracking, acid generation at the slot and concrete interface, and/or debonding were encountered on the non-overlay slotted anode systems at the New Columbia interchange.
